Kealakekua Bay / Captain Cook Monument Snorkel

Kealakekua Bay stands out as one of the Big Island's most spectacular snorkeling destinations, where Captain Cook first set foot in Hawaii centuries ago. These protected waters along the Kona Coast offer incredible visibility and teem with marine life, creating an underwater paradise that snorkelers dream about. Coral Reef Snorkel Adventures takes you there aboard the Manta Raiv, a nimble RHIB vessel that keeps groups small – just 14 guests maximum – so you get that personal touch you won't find on crowded tour boats.

The adventure unfolds over 3.5 hours, starting with a scenic 30-minute cruise from Honokohau Harbor. Your US Coast Guard certified captain isn't just skilled at navigating these waters; they're storytellers who bring Kona's rich history and marine ecosystem to life during the journey. Once you reach Kealakekua Bay / Captain Cook Monument, you'll have a full hour to explore underwater – plenty of time to really soak in the experience rather than feeling rushed.

What makes this Kealakekua Bay / Captain Cook Monument snorkel tour in Kailua-Kona truly special is what you'll encounter below the surface. Yellow tangs dart between coral formations like living sunshine, while parrotfish graze peacefully nearby. Green sea turtles frequently glide through these sanctuary waters, and if you're lucky, you might find yourself swimming alongside one of these gentle giants. Professional snorkel guides stay close to help spot marine life and share insights about coral reef behavior that you'd never notice on your own.

Everything you need comes included – quality masks, fins, snorkels, and flotation devices that actually fit properly. Between the boat ride and snorkeling, you'll enjoy fresh tropical fruit, snacks, bottled water, and other refreshments. The small group size means guides can give you individual attention, whether you're a first-timer who needs encouragement or an experienced snorkeler wanting to know more about what you're seeing.

At $99 per person, this tour welcomes ages 7-70 with a 270-pound weight limit, and all minors need an adult supervisor along. You'll meet at Honokohau Harbor on Kealakehe Parkway – just arrive 15 minutes early for check-in. Need to cancel? No problem with 24 hours notice for a full refund. Want the whole boat to yourselves? Private charters run $1,299 for up to 14 people, and you can add GoPro rentals for $50 to capture those magical underwater moments.
